MAURICE SGHEUER, OF NEW YORK, N. Y., ASSIGNQR T0 AMERICAN BELT CORPORA- TION, OF NEW YORK, N. Y., A CORPORATIONOF NEW YORK.

STRETCHABLE LEATHER.

Specification of Letters Patent.

Patented June is, 1916.

Application filed November 19, 1913. Serial No. 801,861.

To all whom it may concern Be it known that I, MAURICE Son'nunn, a citizen of the United StatesQresiding at New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in stretchable Leather, of which the following is a specification. I

My invention relates to elastic or stretchable fabrics and a method of making the same and my objects are the production of this material in a cheap, easily worked form and in which the highest degree of elasticity will be imparted to the fabric.

The drawings are highly exaggerated representations of the structure for clearness of illustration.

Figure 1 is a view of the prepared fabric, Fig. 2 a view of the fabric after the elastic medium has been applied and Fig. 3 a View of a modified form in which the treated fabric has been mounted on an elastic web.

To produce my material I take a piece of fabric, 1, generally leather, and crimp or corrugate it in a direction at right angles to the direction of stretching, preferably by passing it between milled rolls. The corrugated fabric is next laid, face down, on a support and a suitable elastic medium, preferably in liquid form, such as rubber cement, is poured on the back and permitted to dry, filling the corrugations and forming a layer of elastic material 2 on the back of the fabric. If additional body is required the flattening of the corrugations and return to its initial length upon releasing the strain due to the contraction of the elastic medium or the mounting or both. Elasticity in two or more directions may be imparted to fabrics by corrugating them in two or more directions.

It is obvious that any non-elastic fabric may have the property of elasticity imparted to it by the method herein described.

I claim 1. stretchable material composed of a sheet of corrugated fabric, a layerof elastic medium on one side thereof filling the corrugations and a sheet of elastic material secured thereto on the coatedside.

2. Stretchable material composed of a sheet of corrugated fabric and a backing of elastic medium substantially filling thecorrugations and forming a continuous coating thereon.

In testimony whereof I have afiixed my signature in presence of two witnesses.

MAURICE SCHEUER.
